What this PR does / why we need it:

This PR is the first step to implement the proposal #8221 .

includes:

1. now registry can use the TLS secrets by user created, and listen on port 443 by default with the TLS certificate.

2. now registry supports htpasswd as basic authentication.

3. now registry strips out the configuration items to ConfigMap, user has a more detailed configuration strategy.

Special notes for your reviewer:

I'd like to test this feature at CI, but I don't know how to add the testcase, any suggestions are greatly appreciated.

Does this PR introduce a user-facing change?:

Add TLS and authentication support to container registry (using new variables `registry_tls_secret`, `registry_htpasswd`, `registry_config`)

Hi @zhengtianbao. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
